Multi-stage electrocatalytic oxidation wastewater treatment device

Abstract

The invention is applicable to the field of wastewater treatment, and provides a multistage electrocatalytic oxidation wastewater treatment device which comprises a treatment box, a partition plate is fixedly connected to the interior of the treatment box and divides the interior of the treatment box into a mounting chamber and a treatment chamber, and a water inlet pipe and a water outlet pipe are arranged on the side face of the treatment box. The water inlet pipe and the water outlet pipe are located on the two sides of the treatment box, and two first mounting boxes are fixedly connected to the inner top wall of the treatment box. Multi-stage electro-catalysis is used, and different oxidants are introduced, so that the wastewater treatment effect is greatly enhanced; the gear drives the telescopic rod to swing, and the telescopic rod drives the scraping plate to scrape dirt on the surface of the electrode plate, so that the condition that dirt is generated on the surface due to long-time operation of the electrode plate is avoided, and the wastewater treatment efficiency is improved; the stirring mechanism repeatedly stirs the wastewater, so that ozone and hydrogen peroxide are quickly and uniformly mixed with the wastewater, the electro-catalysis effect is improved, and the wastewater treatment effect is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, in particular to a multi-stage electrocatalytic oxidation wastewater treatment device. Background technique [0002] Electrocatalytic oxidation technology is an oxidation reaction that uses electricity as a catalyst and hydrogen peroxide, oxygen, ozone, etc. as an oxidant. Electrocatalytic oxidation is considered to be the most advantageous treatment method in advanced oxidation technology. It uses oxidizing substances such as hydroxyl radicals generated on the surface of electrodes to degrade pollutants in wastewater. Because it does not need to add any chemicals, it is green and environmentally friendly. The degradation efficiency is high, and it has been rapidly developed and widely used. [0003] However, in the process of electrocatalytic oxidation treatment of wastewater, there will be the following problems: first, when the oxidant is introduced, the oxidant cannot be quickly and unifo...
